This evaporation material requires e-beam evaporation with a water-cooled copper hearth. Compatible liners include graphite, Al2O3, BN, or Ta to prevent contamination at high melting point.
- Evaporation Method: E-beam evaporation is required due to the high melting point of tungsten.
- Hearth Cooling: The water-cooled copper e-beam hearth prevents thermal damage during evaporation.
- Liner Compatibility: Use graphite, Al2O3, BN, or Ta liners to avoid chemical reaction with molten tungsten.
- Vacuum Environment: Deposition must be performed under high vacuum to achieve thin-film quality.
How does the pellet size of 1–3 mm influence the evaporation behavior of tungsten in e-beam deposition?
The pellets are sized 1–3 mm to support source loading and consistent evaporation. This narrow size range ensures uniform melting in the water-cooled copper e-beam hearth, reduces the risk of spitting, and helps maintain a stable evaporation rate for high-quality thin films.
What liner materials are recommended for tungsten evaporation and why is liner selection important?
Compatible liners include graphite, Al2O3, BN, and Ta. Liner selection is critical because tungsten's high melting point of 3410°C can cause chemical reactions with incompatible materials, leading to film contamination. The listed liners provide thermal stability and chemical inertness for clean deposition.
What documentation should be reviewed before procuring tungsten evaporation pellets for laboratory use?
The supplier recommends reviewing the Certificate of Analysis, safety data sheet, shipment conditions, and export requirements against laboratory use requirements. This ensures the material meets the specified 99.95% purity and that handling, storage, and shipping comply with safety and regulatory standards.
This Tungsten evaporation material in pellet form (99.95% purity, 1-3 mm) is suitable for e-beam evaporation with water-cooled copper hearths, but its high melting point requires careful matching to deposition hardware and process parameters.
Positive
- High purity and defined pellet size: The 99.95% purity and 1-3 mm pellet form enable consistent deposition behavior and straightforward source loading for e-beam evaporation workflows.
- Compatible with common e-beam setups: Explicitly compatible with water-cooled copper e-beam hearths and graphite/Al2O3/BN/Ta liners, facilitating integration into standard thin-film deposition systems.
Trade-offs
- High melting point requires specialized equipment: With a melting point of 3410°C, this material demands high-temperature evaporation sources and careful thermal management, limiting compatibility to systems with adequate power and liner choices.
- Deposition-source geometry must be confirmed: The product's pellet form and size require exact matching to the evaporation source geometry (e.g., hearth dimensions and liner type) to avoid loading issues or incomplete evaporation.
